FASTENING DEVICE FOR R-IBBED EXPANDED-METAL PEQD'UCT.

Application filed August 26, 1913. Serial No. 786,750.

.T 0 a]! whom. it may concern Be it. known that I, ARTHUR lV. HERBERT, a citizen of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements iii Fastening Devices for Ribbed Expanded-llletal Products, of which the following is a specification. i This invention relates to novel fastening means for expeditiously and securely fastening expanded sheet metal, such as metal lathing, to I-beams or other supports, and possesses special utility in its application as a fastener for expanded sheet metal which acts as self-centering when secured to beams or other permanent supports in fireproof building structures.

' To this end, the object of the invention is to provide a simple and practical fastening device of the character indicated which may be readily and economically manufactured from a'sheet metal blank by stamping-process, while at the same time providing a fastener which may be easily and quickly applied and securely locked in place by a simple operation of applying pressure thereto by a pair of pliers or equivalent tool.

Other objects. and advantages of the present device will readily appear to those skilled in the art, as the description of the same proceeds, and the nature thereof is better understood in connection with the accompanying drawings wherein a preferred and practical form of the invention is'disclosed.

Figure l is a plan view of a section of a ribbed expanded metal sheet resting upon a beam, and showing the application of the invention. Fig.2isa'crosssectioual'view of the structure shown in Fig. 1. Fig. 3 is a detail elevational view showing how the device forming the subject matter of this invention is locked in place. Fig. 4 is an elevational view showing the device locked in place. Fig. 5 is a perspective view of the invention. Fig.0 is a perspective view of a modificw tion.

Similar reference. characters designate corresponding parts throughout the several figures of the drawings.-

The invention is specially adapted for use in connection with expanded sheet metal I products such as metal lathing which have upstanding longitudinal ribs formed in- Speeificatiou of Letters Patent.

.tegral therewith, and for the purposes of ordinarily employed for fastening metal self-centering, or metal lathing to I-beams or other supports. the present invention provides a clip-like element for this purpose and the same operates to securely clamp the metal sheets to the I-beams Or other support in such a manner as to prevent displacement or movement thereof in any direction While the concrete or other plastic material is be ing applied thereto.

The improved clip preferably consists of a single stamping made from sheet metal the same being pressed up to assume the gen eral form shown inthe. drawings, and desig nated inits entirety by the reference character 1. The device includes a body-web 2, which is provided with a centering and rib clearance notch .3, and with the parallel wings 4: extending to one side of the body web 2. and having the substantially angularly disposed leg members The uncon nected terminals of the legs 5 are formed with the curving holdinghooks 6 having terminal projecting engaging feet adapted to engage under and a ainst a flange of an I-beam I. The body-web 2 has also integrally formed therewith as at 9 an integral locking tongue 8 which is bent to the side of the body-web 2 opposite the wings i. This tongue 8 has in its free end portion a rib engaging notch 10 which is adapted to engage the rounded crown of one of the metal ribs R. I

The modification disclosed in Fig. 6 is similar to the form of the invention shown in Fig. 5 exccptin the particular of not b eiug provided in its body-Web 2 with the centerin and clearance notch 3, but instead imsizamtiail dzwtzi and iii" light b aiding pmitiu be GbSEIVGii m handing the :35: b6523 of the 015;
